| 中文摘要 | 本文提出一個植基於算術編碼法的動態使用者階層關係配置法。我們 的方法中,每一位使用者配置一副金匙配對(K,T),其中K是一個介於0 與1之間的實數,T.則為一整數。任兩位使用者的階層關係,可藉由執行 一簡單的數學公式得出。並且,當一位新使用者加入此使用者階層系統時 ,我們可以很快速地配置一金匙配對給他,而且對於系統內其他使用者的 金匙配對不會有所影響。此外,當系統中有使用者離開時,只有相關使用 者的金匙配對需要修改。 |
| 英文摘要 | In this paper, a dynamic user hierarchy mechanism based on arithmetic coding is proposed. Our scheme assigns each user a key pair (K,T), where K is a real number between zero and one, and T is an integer. Then, the relationship between two users can be easily revealed by performing a simple formula to the key pair. In addition, whenever a user is inserted into the user hierarchy system, the corresponding key pair can be determined quickly without changing any existing key pairs. Furthermore, whenever a user is deleted from the system, only some relevant keys are needed to be modified. |
